  Heavy rains are among the natural hazards that knowledge of their temporal and spatial distribution helps to reduce potential damage. For this purpose, the existence of a significant relationship between widespread precipitation and topographic indices of Alborz mountainous region has been investigated. In this study, Pearson correlation test was used and in this model, the dependent variable of total daily precipitation of the study area (precipitation occurred in more than 70% of synoptic stations in the area) and the independent variable of data related to topographic indicators of the study area (station height Synoptic, station slope and direction, longitude and latitude of the station, distance from the northern baseline, distance from the ridge, average height of the station in a radius of 2.5 km, average height of eight blocks fifty km in eight geographical directions to the center of the synoptic station, height difference Its average is eight blocks from the average height of the station in a radius of 2.5 km). First, the correlation between precipitation (129 days) and topographic indices based on common synoptic stations in three seasons of winter, spring and autumn was identified and then the correlation coefficients with 95% confidence interval at a significance level less than 0.05 were investigated. Each season, a sample day with the highest correlation coefficients in the majority of topographic indices was selected as the representative of that season. The study area, which is the vast Alborz mountain range, has been divided into areas with topographic and climatic similarities due to the complexity of topography and the diversity of its climatic conditions in each area. The highest number of significant statistics in terms of temporal and spatial scale between widespread precipitation with topographic indices is related to widespread precipitation in spring with 18 cases and the lowest is related to widespread precipitation in winter with 9 cases in autumn 14 cases of significant linear relationship have been identified. Among the topographic indices, the strongest index is related to the difference between the average height of blocks 50 km from the average height of the station in a radius of 2.5 km in different directions according to different seasons of the year and Evidence of the effect of direction on inclusive rainfall in the study area and that the area is in a certain direction to receive more rain , meaning that the mass of humid air entering from the northern parts of the country, including Siberian high pressure (Babaei Fini, 1393) due to low altitude and proximity to the ground is affected The surface roughness is located and the mass of moist air entering from the northwestern and western parts of the country, including the western migratory high pressures (Qashqaei, 1375), (Moradi, 1385)) due to higher altitude and more power is less affected by surface roughness. And the region's precipitation is affected by these high-level atmospheric systems. On the other hand, widespread precipitation in the northwestern and south-central Alborz region has the highest and the lowest south-western Alborz region has a significant linear relationship with the values of topographic indices. The results of this study have a significant linear relationship with most topographic indices (22 indices out of 24 Index) with widespread precipitation to be able to estimate and predict the most effective indices affecting precipitation in the region. The two topographic indices for the station and the distance from the ridge did not enter the correlation model on any day and in any area of the study area and did not establish any significant linear relationship, albeit weakly, with the total precipitation of the area Manuscript profile

  Organizational communication includes a process in which two or more units of a group exchange the information they need through an exchange of opinions, and since communication is one of the primary elements of management, managers must communicate effectively with the people of the group or their peers at different levels. establish that this research is a mixed research design of an exploratory type, so quantitative and qualitative data are combined with each other by the method of connecting data, that is, connecting two sets of data by building one on the basis of the other. In the following, using in-depth and semi-structured interviews with 15 managers of the national sample using the snowball interview technique, and after theoretical ghosting, the collected data sets were organized using MAXQDA10 software and coding techniques. Then, for scaling, the calculation of face validity, content validity (CVR) and (CVI) and exploratory and confirmatory factor analysis were used, and by distributing 500 questionnaires among 25 executive bodies of Gilan province and collecting 429 questionnaires, hypotheses were tested using the Pearson correlation method. Conducting and confirming all hypotheses and the final research model for the communication skills of managers in government organizations including information exchange, feedback, situational, technology application, analytical-perceptual, cognitive-behavioral and social skills were presented.
